The concept of model-based testing (MBT) is an evolving software testing approach that involves generating test cases automatically from models created by software developers and testers. This approach allows for a more integrated piece of modern test automation, where the responsibility to create testable applications is shared among the development team. MBT has several benefits, including creating better software quality, reducing test suite maintenance, and increasing flexibility in testing, but it also poses challenges such as training the development team on model-based testing and investing significant upfront time for initial implementation of the tool. By incorporating modeling into the development workflow, MBT can help ensure that specifications are reinforced at the beginning of the discovery stage and design bugs are found before code even exists, ultimately leading to a more thorough and efficient testing strategy.
